The remote village of Nunam Iqua is located about 160 miles northwest of Bethel. (AccuWeather) Four children between the ages of 2 and 14 were found alive, but suffering from severe hypothermia, on Monday after becoming lost in a blizzard for 27 hours near Nunam Iqua, Alaska, a remote community with a population of less than 200, according to the 2010 census.Alaska State Troopers have...
Stories of unique and sentient interactions between elephants and their dead are a familiar part of the species' lore, but a comprehensive study of these interactions has been lacking—until now. A recent review of documented field observations of elephants at carcasses reveals patterns of elephants' behavior toward their dead, regardless of the strength of former relationships with the deceased...
A new study on how and when the precursors to eggs and sperm are formed during development could help pave the way for generating egg and sperm cells in the lab to treat infertility.
Spitzer became first telescope to directly capture light from planets in orbit around other stars Nasa has ended science operations on its Spitzer infrared space telescope and placed the instrument into safe mode.The mission officially ended at 2230 GMT on 30 January 2020. Spitzer was one of Nasa’s four “great observatories”, alongside the Hubble space telescope, the Chandra X-ray...
The only known freshwater harbor seals in the U.S. should be listed as as threatened or endangered, an environmental group said Thursday in its second petition for the animals.
Photosensitizers are molecules that absorb sunlight and pass that energy along to generate electricity or drive chemical reactions. They're generally based on rare, expensive metals; so the discovery that iron carbenes, with plain old iron at their cores, can do this, too, triggered a wave of research over the past few years. But while ever more efficient iron carbenes are being discovered,...
Engineers with the University of Cincinnati have created a tiny portable lab that plugs into your phone, connecting it automatically to a doctor's office through a custom app UC developed.
We asked a dermatologist to explain why some men lose their hair, and why male pattern baldness can strike early in...
Italian American organized crime may conjure images of classic gangster flicks, but as James B. Jacobs explores in the Crime and Justice article "The Rise and Fall of Organized Crime in the United States," its history is unexpectedly nuanced and mutable. The Cosa Nostra families—popularly known as the Mafia—operated, at the height of their power, in at least twenty-four American cities, with...
A storm forecast to affect the Northwest this weekend will split into two parts -- and one of the pieces will take aim at Southern California and the southwestern United States, dragging chilly air back into the region by early next week.The storm is expected to bring some rain and mountain snow, including at pass levels, to the region. Travel hazards will accompany the beneficial rain and snow...
As the effects of climate change become more evident, more than half of U.S. adults (56%) say climate change is the most important issue facing society today, yet 4 in 10 have not made any changes in their behavior to reduce their contribution to climate change, according to a new poll by the American Psychological Association.
Forecasters use a variety of satellite imagery to understand what is happening in a storm, and sometimes just a visible picture can tell a lot. NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of the Tropical Storm Francisco in the Southern Indian Ocean that showed wind shear was pushing clouds away from the storm's center.
The low-pressure area that formed off Australia's Kimberley coast and lingered there for a couple of days has moved west and developed into Tropical Cyclone Damien off the Pilbara coastline. NASA's Terra satellite passed over the Southern Indian Ocean and provided forecasters with a visible image of the new tropical storm. The Pilbara Coast is also known as the northwest coast of Western...
A research team from the University of Delaware and the Indian Institute of Management took a deeper look into the newly emerging domain of "forward-looking" business strategies and found that firms have far more ability to actively influence the future of their markets than once thought.
In a recent study, University of Arkansas physics researchers found evidence of an inverse transition in ferroelectric ultrathin films, which could lead to advances in development of data storage, microelectronics and sensors.
Photosensitizers absorb sunlight and pass that energy along to generate electricity or drive chemical reactions. Scientists watched what happened when light hit an inexpensive photosensitizer, iron carbene, and discovered it can respond in two competing ways, only one only one of which allows electrons to flow into the devices or reactions where they're needed. It took this desired path about 60%...

Proposed a century ago, inverse transitions seem to contradict the fundamental law that disorder increases with temperature. They have been found in superconductors and liquid crystals, but not yet in ferroelectric materials, which have a variety of uses in electronics and data storage.
Children with higher concentrations of a certain chemical in their blood are more likely to get cavities, according to a new study. Researchers found that higher concentrations of PFAS were associated with greater tooth decay in children.
Genetically edited immune cells can persist, thrive, and function months after a cancer patient receives them.
Scientists have developed the most advanced disease model for blood vessels to date and used it to discover a unique role of the endothelium in Hutchinson-Gilford Progeria Syndrome. This devastating and extremely rare genetic disease causes symptoms resembling accelerated aging in children. The model is the first to grow both the smooth muscle and inner lining, or endothelium, layers of blood...
The protein tau has long been implicated in Alzheimer's and a host of other debilitating brain diseases. But scientists have struggled to understand exactly how tau converts from its normal, functional form into a misfolded, harmful one. By analyzing brain tissue from patients, researchers have revealed that modifications to the tau protein may influence what type of disease that will develop --...
Scientists have identified a molecular 'switch' that controls the immune machinery responsible for chronic inflammation in the body. The finding could lead to new ways to halt or even reverse many age-related conditions, from from Alzheimer's and Parkinson's to diabetes and cancer.
After identifying a molecular pathway that allows nonalcoholic steatohepatitis (NASH) to progress into liver cell death, researchers were able to use these pathways to halt further liver damage.
New research has deciphered how rogue communications in blood stem cells can cause leukemia. The discovery could pave the way for new, targeted medical treatments that block this process.
From plastics to pesticides, it seems like every week delivers fresh news about the dangers of endocrine disruptors -- chemicals in the environment that alter the body's hormones and can lead to reproductive, developmental, neurologic and immune problems and cancer. Industry regulation and individual consumer choice can reduce exposure to such chemicals, but there are few options to counteract...
Methanol is a versatile and efficient chemical used as fuel in the production of countless products. Carbon dioxide (CO2), on the other hand, is a greenhouse gas that is the unwanted byproduct of many industrial processes. Converting CO2 to methanol is one way to put CO2 to good use. Chemical engineers have now demonstrated how to make that conversion process from CO2 to methanol more efficient by...
Scientists used biochemical experiments and cryo-electron microscopy (cryo-EM) to determine the atomic structure of a complex assembly of molecules known as the histone mRNA three-prime (3') end-processing machine. This machine plays a fundamental role in proper activity and duplication of the cell genome and when defective, it may lead to human diseases, including cancers.
Scientists have uncovered the underlying rules that, when broken, contribute to neurodegenerative diseases such as ALS.
The situation is extraordinary: there have only ever been four declarations of public health emergencies of international concern in the past and now there are two at the same time.
